Once there was only a most wise person. He thought that he is the only person having all intelligence.
People always come to him to take advice and the wise person thought due to his advice only people is getting smarter. And this way gradually he got his arrogant. And due to his arrogant nature he thought if he continue helping people his value to them become less. So he decided to hide his all intelligence in an earthen pot in any isolated place. But his son got sell of his secret and became excited to know all scene.
So son started following his father. Once son found that his father (wise person) was going out of the house by holding an earthen pot. Son followed his father, finally the wise person reached to a very tall tree (because he wants to hide his all intelligence on very top of tree). Now he tides the earthen pot on his chest and started climbing on tree. Since the earthen pot was on his chest he was not able to climb on tree. His son was watching this entire story. And son suggested his father to hold the pot on his back so that he can easily climb on tree.
The wise person became astonished now he thought that he has put his all his intelligence in the pot and he has nothing more. So he dropped the pot on ground and this way the pot got broken and intelligence got spread to all mankind.
